[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-9 This invention provides a technical solution that enables convenient and quick installation of surge protectors, and the installed surge protector has stable performance. Furthermore, during installation, it can remain in different installation states for subsequent maintenance and debugging. A three-phase surge protector with manually resumable feedback state includes a main component 100, comprising an inlet component 200 fixed to the top of the main component 100, a current-guiding component 300 screwed into the inlet component 200, an outlet component 400 fixed to the bottom of the main component 100, a surge protector component 500 located at the opening of the main component 100, a plug-in component 600 fixed to the back end of the surge protector component 500, a mounting component 700 sliding inside the bottom end of the main component 100, a track component 800 fixed to the top of the mounting component 700, and a limiting component 900 fixed to the bottom front end of the main component 100. After inserting the surge protector component 500 into the main component 100… By pulling the limiting component 900 to release the restriction on the mounting component 700 and pushing the mounting component 700 upward, the mounting component 700 moves the plug-in component 600 and the surge protection component 500 into the main component 100, thus completely installing the surge protection component 500. The surge protection component 500 installed in this way has an anti-loosening effect. Continuing to push the mounting component 700 upward will move the track component 800 upward, and the track component 800 will drive the flow guiding component 300 to contact the surge protection component 500, thus allowing the surge protection component 500 to enter the working state. At this time, releasing the limiting component 900 will allow it to limit the mounting component 700 again, completing the installation of the surge protection component 500. Compared with the existing technology, this avoids brute force installation of the surge protection component 500, making the installation of the surge protection component 500 more convenient and labor-saving, and allowing the main component 100 to continue to be used stably even after multiple replacements of the surge protection component 500.

[0019] Specifically, such as Figure 3In the main component 100, there is a housing 101. The front end of the housing 101 has a groove for installing the surge protection component 500. The front end of the housing 101 is provided with a plug-in slot 102. There are eight plug-in slots 102 on the upper and lower sides of the groove of the housing 101, and the eight plug-in slots 102 correspond to four surge protection components 500. The housing 101 has an inner cavity 103 inside. The center of the housing 101 is provided with an inner groove 104. There are four inner grooves 104 at the front end of the housing 101 corresponding to the eight plug-in slots 102. Gaskets 105 are fixed to the upper and lower sides of the front end of the housing 101 corresponding to the inner grooves 104. The gaskets 105 can make the surge protection component 500 more secure and less prone to shaking during installation.

[0020] Furthermore, such as Figure 4 , 5 In the process, the inlet component 200 includes a first guide plate 201 fixed inside the top of the housing 101. Each recessed groove 104 has a first guide plate 201 at its top, so there are four first guide plates 201. The bottom of the first guide plate 201 is provided with a threaded groove 202. In use, the wire is inserted from the top of the housing 101 into the first guide plate 201, and the wire is reinforced by turning the screw at the corresponding position.

[0021] Furthermore, such as Figure 5 In the process, the flow guiding assembly 300 includes an external threaded shell 301 screwed into the threaded groove 202, a flow guiding block 302 sliding at the port of the external threaded shell 301, a spring 303 fixed to the end of the flow guiding block 302, an insulating disk 304 fixed to the spring 303 inside the external threaded shell 301, and a connecting rod 305 fixed to the end face of the insulating disk 304. The connecting rod 305 and the insulating disk 304 are made of insulating material. The connecting rod 305 passes through the external threaded shell 301 and has a rotating roller 306. In use, when the track assembly 800 moves upward, it will drive the roller 306, the connecting rod 305, and the insulating disk 304 to move towards the opening of the external threaded shell 301. The insulating disk 304 will squeeze the spring 303 and the flow guiding block 302 to contact the top contact of the lightning protection assembly 500, so that the wiring at the top of the housing 101 is connected to the lightning protection assembly 500 through the first guide plate 201, the external threaded shell 301, and the flow guiding block 302.

[0022] Furthermore, such as Figure 4 In the middle, the discharge component 400 includes four secondary conductors 401 fixed inside the bottom end of the housing 101. The top of the secondary conductor 401 is provided with a bent end 402. The bent end 402 can be more secure when it contacts the bottom contact of the surge protection component 500 and the secondary conductor 401. The connecting conductors 403 fixed between the secondary conductors 401 are used to connect the secondary conductors 401 to the ground wire by inserting the ground wire from the bottom of the housing 101 to the secondary conductor 401 and reinforcing it with the screws at the corresponding locations. Since the secondary conductors 401 are connected by the connecting conductors 403, the secondary conductors 401 can be connected to the ground wire.

[0023] Furthermore, such as Figure 6 In the middle, the lightning protection component 500 includes a surge protector 501 disposed at the opening of the housing 101. The surge protector 501 uses the energy pulse of a lightning strike to activate the coil of a magnetically latched signal relay, and provides a lightning protection alarm to the charging pile through the change of contact state. Furthermore, the magnetic latching relay coil can be reset manually by powering it with a reverse pulse signal. The protective shell 502, fixed at both ends of the surge protector 501, prevents damage to the contacts of the surge protector 501 when the surge protector 501 is inserted into the housing 101. The protective shell 502 has a slot 503 at the tail end of the surge protector 501, and the surge protector 501 has a guide plate 504 at the slot 503. In use, when the surge protection component 500 needs to be installed, the protective shell 502 on the surge protector 501 is inserted into the insertion slot 102. Because the protective shell 502 at both ends of the surge protector 501 is snapped into the insertion slot 102, the surge protector 501 is not easy to shake after installation, and can then be quickly installed through subsequent structures.

[0024] Furthermore, such as Figure 6 In the middle, the plug-in assembly 600 includes a bracket 601 fixed to the tail end of the lightning protection assembly 500, and a round rod 602 rotatably inside the bracket 601. The bracket 601 and the round rod 602 can be inserted into the recessed groove 104.

[0025] Furthermore, such as Figure 7 , 8 In the mounting assembly 700, a drive rod 701 slides within the inner cavity 103. The top of the drive rod 701 has a groove 702, which is an inclined groove. The groove 702 serves to pull the round rod 602. The bottom of the drive rod 701 has a vertical groove 703. The groove 702, vertical groove 703, and round rod 602 are compatible. The bottom of the drive rod 701 has a limiting groove 704, and the end face of the drive rod 701 has three fixing grooves 705 located at the limiting groove 704. During use... When the surge protector 501 is inserted into the housing 101, the surge protector 501 will drive the bracket 601 and the round rod 602 to insert into the recessed groove 104. At this time, the round rod 602 abuts against the end face of the track assembly 800. By pushing the drive rod 701 upward, the round rod 602 will enter the pull groove 702 and move to its bottom. The inclined surface of the pull groove 702 will pull the round rod 602, the bracket 601, the surge protector 501 and the subsequent structure, which will connect the guide plate 504 and the second guide plate 401 at the bottom of the surge protector 501.

[0026] Furthermore, such as Figure 7In the track assembly 800, there is an extension block 801 fixed to the top of the drive rod 701. The extension block 801 has a fork in the middle to allow subsequent structures to be installed. The side end of the extension block 801 is provided with a delay groove 802. The extension block 801 is provided with a push groove 803 at the bottom of the delay groove 802. In use, when the drive rod 701 moves upward, it will drive the extension block 801 to move upward. As a result, the roller 306 moves to the bottom of the delay groove 802. When the drive rod 701 drives the extension block 801 to move upward again, the roller 306 will move from the delay groove 802 to the bottom of the push groove 803. Since the push groove 803 is inclined, the push groove 803 will push the roller 306, the connecting rod 305, the insulating disc 304, the spring 303, and the guide block 302, so that the guide block 302 can contact the guide plate 504 on the top of the surge protector 501, thereby connecting the wiring on the top of the housing 101 and the surge protector 501.

[0027] Furthermore, such as Figure 9 In the middle, the limiting component 900 includes a limiting tube 901 that slides within the limiting groove 704, a pull rod 902 that slides at the open end of the limiting tube 901, the pull rod 902 being fixed to the housing 101, a tension spring 903 fixed between the limiting tube 901 and the pull rod 902, and a locking block 904 fixed to the outer wall of the pull rod 902. The locking block 904 is adapted to the fixing groove 705. In use, before pushing or pulling the drive rod 701, it is necessary to pull the pull rod 902 to cause the locking block 904 to disengage from the fixing groove 705, because the fixing groove 705 has The three fixing slots 705 correspond to the initial state, the installation state, and the connection state. The initial state is when the surge protector 501 is inserted into the housing 101. The installation state is when the surge protector 501 is installed. The connection state is when the top guide plate 504 of the surge protector 501 is connected to the guide block 302. In this state, the surge protector 501 can work. Because the locking block 904 can be locked in the fixing slot 705 to limit the drive rod 701, the equipment can be in one of the three states, making the equipment convenient for installation, disassembly, and maintenance.

[0028] When using the surge protector 500, the protective shell 502 on the surge protector 501 is inserted into its socket 102. Because the protective shells 502 at both ends of the surge protector 501 are snapped into the socket 102, the surge protector 501 is not easy to shake after installation. When the surge protector 501 is inserted into the shell 101, the surge protector 501 will drive the bracket 601 and the round rod 602 to insert into the recessed groove 104. At this time, the round rod 602 abuts against the end face of the track assembly 800, pushing the drive rod 701 upward. This causes the round rod 602 to enter the groove 702 and move to its bottom. The inclined surface of the groove 702 pulls the round rod 602, the bracket 601, the surge protector 501, and subsequent structures, connecting the guide plate 504 and the second guide plate 401 at the bottom of the surge protector 501. When the drive rod 701 moves upward, it drives the expansion block 801 upward, thereby moving the roller 306 to the bottom of the delay groove 802. When the drive rod 701 drives the expansion block 801 upward again, the roller 306 will move from the delay groove 802 to the bottom of the delay groove 802. When the sliding groove 802 moves to the bottom of the push groove 803, because the push groove 803 is inclined, it will push the roller 306, connecting rod 305, insulating disc 304, spring 303, and guide block 302, so that the guide block 302 can contact the guide plate 504 on the top of the surge protector 501, thereby connecting the wiring on the top of the housing 101 with the surge protector 501. At this time, the surge protector can enter the working state. Before pushing or pulling the drive rod 701, the pull rod 902 needs to be pulled to disengage the locking block 904. The fixed slot 705 has three slots, which correspond to the initial state, the installation state, and the connection state. The initial state is when the equipment inserts the surge protector 501 into the housing 101. The installation state is when the surge protector 501 is installed. The connection state is when the top guide plate 504 of the surge protector 501 is connected to the guide block 302. In this state, the surge protector 501 can work. Because the locking block 904 can be locked in the fixed slot 705 to limit the drive rod 701, the equipment can be in one of the three states.

[0029] In summary, the surge protector 501 can be installed conveniently and quickly through the main component 100, the inlet component 200, the flow guiding component 300, the plug-in component 600, the installation component 700, the track component 800, and the limiting component 900. This makes the surge protector 501 more stable after installation, prevents it from falling off, and has multiple installation stages, making it more suitable for maintenance work during the installation and disassembly of the surge protector 501.
